| 摘 要： | 南四湖二级坝第三节制闸扩建工程地基有液化的可能,根据勘探资料,对可液化地基的加固方法进行了比较;通过灌浆加固后取样的水泥含量、无侧限抗压试验等对比研究,对纯水泥浆和水泥与黏土等4种不同配合比灌浆材料的可行性进行了研究,推荐了实际工程加固的施工工艺参数。工程实施情况表明,选择的灌浆材料是可行的。

| Abstract: | In consideration of the fact that ground liquefaction might occur in the second floodgate extension project of Nansihu grade-Ⅱ dam,the consolidation methods for the liquefiable ground were compared based on the investigated data.By cement content and unconfined compression tests on samples after grouting consolidation,a feasibility study was performed on 4 kinds of grouting materials,such as pure cement mortar,cement and clay,etc.with different mixing ratios, and rational construction parameters were recommended.The results show that the recommended grouting materials are feasible. |
